Vajrasana

Vajra is the thunderbolt — the weapon of Indra, and in the subtle anatomy the name of the channel connected with the pelvic region. The Gheranda Samhita describes the pose simply: kneel with the feet turned back and sit upon the heels, firm as the vajra. Its classical reputation is unique among asanas: it is the one posture traditionally practised directly after eating, said to aid digestion by gathering the blood and prana into the belly while the legs rest folded. For practitioners who cannot sit cross-legged, it is the tradition''s first gift — an upright, steady seat for pranayama and meditation that asks almost nothing of the hips.

• Provides a stable, upright kneeling seat for pranayama and meditation
• Stretches the tops of the feet and ankles
• Traditionally supports digestion when practised after meals
• Gently loads the knees in flexion, useful for healthy knee mobility
• Requires little hip flexibility, making it accessible where cross-legged seats are not

1. Kneel with the knees together and the tops of the feet on the floor, toes pointing back.
2. Sit back so the sitting bones rest on the heels, keeping the spine tall.
3. Rest the hands on the thighs and let the shoulders soften.
4. Breathe steadily; for digestion, sit for five to ten minutes after meals.
5. To come out, lean forward onto the hands, lift the hips, and stretch the legs out one at a time.

• Sitting with the knees splayed apart: keep them together for the traditional form.
• Forcing the pose with painful knees: use a folded blanket behind the knees or under the ankles.
• Rounding the spine while seated: lengthen up through the crown as in any seated pose.
• Practising for long periods with untrained ankles: build duration gradually.

• Easier: place a folded blanket under the ankles or between the calves and thighs.
• Easier: sit on a low block placed between the heels rather than fully on the heels.
• Harder: extend into Supta Vajrasana, reclining back from the kneeling position.
• Harder: combine with Vajrasana breathing practices held for extended meditation sits.

As the seat associated with digestion, Vajrasana is often paired with slow diaphragmatic breathing after meals, the gently compressed abdomen and upright spine supporting a settled, downward-moving energy. It is also used as a base for pranayama by those who find cross-legged postures difficult on the hips.

Vajrasana''s after-meal reputation has received genuine scientific attention: small studies have found that sitting in this kneeling posture after meals reduces gastro-oesophageal reflux and bloating compared with lying down, plausibly by keeping the torso vertical and the abdomen gently compressed. The pose strongly stretches the front of the ankles and the quadriceps, and it gently loads the knee in full flexion — nourishing compression for healthy knees, a problem for injured ones.
